Some weapons still need some minor changes to their quest at least to be realistic at this point in the game. I built my empryean back during the Scars era and upgraded it all the way to 90 I wasn't able to upgrade it past that because of the requirements, and lack of being able to get into a group that actually did VW.
Plates are still difficult to obtain it would be great if more ways to obtain plates were added or it was changed in some way or another to at least be reasonable to work toward again before the game is shutdown.
Possibly even similar changes to Mythics as well, the majority of relics can be solo'd or low manned.
